NAB Hangs when editing Tree grid app

[Bruce.Wilson]

Hello,
I have a Tree grid app that when I try to edit it using NAB, it hangs while loading mask is on the screen. I don't get any errors in the Valence error log, but there are entries in the Apache logs. I tried copying it to a different instance and using a different browser (Edge) but it hangs in both cases. I can edit the actual Tree grid widgit, but not the app.
Here is part of the Apache error log.. (I wasn't sure how to read it)..
ZSRV_MSG0016: URI in request GET /resources/query/codeSnippets/sql.json?_dc=1790083263130&vvInNAB=true&s
ZSRV_MSG0016: URI in request GET /resources/query/codeSnippets/javascript.json?_dc=1790083263394&vvInNAB

ZSRV_MSG0016: URI in request GET /resources/query/codeSnippets/javascript.json?_dc=1790083266034&vvInNAB
Thanks.

I ended up deleting the App and re-creating it, twice. Not sure why it would hang on the loading mask without logging an error in Valence.

Interesting... If it happens again, please open up the browser console (F12) and send a screenshot of any errors that show there. Also please let us know which specific Valence build you're running.
